To make the mix …

Gather
ingredients, a large tub (or wheelbarrow) for mixing, trowel or shovel, and gloves.

In a large bucket or tub, pre-soak sphagnum peat moss or peat coir in warm water, in a two-to-one ratio (2 parts product to 1 part water), until water is absorbed.

Add other inorganic ingredients to the peat mixture. Combine together.

Add organic ingredients and mix.

If using the potting mix right away, then add the appropriate amount of time-release fertilizer for pot size (as indicated in fertilizer instructions.) If saving the potting mix to use later, then store it.
